depending on your definition of sea, yes.
The Caspian sea is actually a lake....but it is freshwater, and i believe (fact check this before you cite it as truth) that the Black sea is freshwater as well.
salinity salinity
No sea exists. The Caspian Sea has a salinity of approximately 1.2%, about a third the salinity of most seawater.
The salinity of the Red Sea ranges from 3.6 to 3.8%.
There are several factors that the Red Sea has high salinity. The Red Sea has a high rate of evaporation and very little precipitation. It also has a limited connection with the Indian Ocean, which has lower water salinity. The Red Sea has a lack of significant rivers or streams draining into the sea.
Saltwater does not have one definite salinity - for instance the salinity of the water in the Dead Sea is different to that of the Atlantic. Indeed the salinity of the sea itself can vary.
Partial answer: The salinity of the dead sea is ~31.5% by weight while the salinity of the Mediterranean is ~3.5%

i believe it is salinity
A hypersaline sea has elevated levels of dissolved ions (salts) as compared to normal saline conditions. A hypersaline sea has about 40 parts per mil salinity and the average salinity for the oceans is about 35 parts per mil salinity.
Salinity of water increase by evaporation.
the saltiness of the sea
33.7%
